（イ）産業上の利用分野
本発明は金属水素化物を利用した熱輸送システムに関す

（ロ）従来の技術
従来、太陽熱集熱器や地熱等のローカルエネルギーの熱

熱した熱を一旦菩熱槽２に貯え、熱媒配管３．４を用い

った。(b) Conventional technology Conventionally, heat transport methods for local energy such as solar heat collectors and geothermal heat have been used, for example, as shown in Fig. 3, in which heat collected by a heat collector 1 is temporarily stored in a heat tank 2. , a method of circulating a heat medium between the heat storage tank 2 and the heat load 5 using the heat medium piping 3.4.
しかし、この上うな熱媒を用いた方法では、輸送中に大
きな熱損失が生じて熱媒の温度時Ｆをもたらし、熱発生
個所での比較的高質の熱が熱利用個所では低質の熱に変
化し、エネルギー的に非常に大きな損失を伴っていた。However, in the method using such a heating medium, a large heat loss occurs during transportation and the temperature of the heating medium becomes F. , and was accompanied by a huge loss in terms of energy.
特に産業用プロセス等において利用する熱は、総熱量と
共に、熱の温度レベルは非常に重要な役割を果し、質の
低］；シた熱は利用価値が無くなるので、熱媒配管の断
熱には極めて断熱効果の高い断熱処理を施さなければな
らなかった。In particular, the heat used in industrial processes, etc., as well as the total heat amount, the temperature level of the heat plays a very important role, and the quality is low. It was necessary to apply heat-insulating treatment with extremely high thermal insulation effects.
更に、太陽熱を利用したシステムでは、エネルギー密度
が小さいため集熱面積が大きくなり、熱利用個所があま

時に太陽熱集熱温度が高くなるに従い集熱効率は低くな
るため、できるだけ集熱温度が低く、温度レベルの低下
が小さい熱輸送か望まれていた。しかし、これまで熱媒
による熱輸送より優る方法は提案されていなかった。Furthermore, in systems using solar heat, the energy density is low, so the heat collection area is large, and the heat medium piping tends to be long even if the heat utilization points are not very far apart. At the same time, as the solar heat collection temperature increases, the heat collection efficiency decreases, so it has been desired to have a heat transport system that keeps the heat collection temperature as low as possible and reduces the drop in temperature level. However, no method superior to heat transport using a heating medium has been proposed so far.

温度レベルと全く同一にすることが可能となる。(d) Means for solving the problem Therefore, the present invention provides two metal hydride containers that are installed at each of the heat generation location and the heat utilization location and connected by hydrogen piping, so that the heat generated at the heat generation location is = Generate hydrogen by supplying it to one metal hydride container, send it to a heat utilization point through one hydrogen pipe, extract and use heat through one metal hydride container, and at the same time generate waste heat. The operation of returning hydrogen from the other metal hydride container on the heat utilization area side to the other cooled metal hydride container on the heat generation area side via the other hydrogen piping is carried out in an alternating manner. 4. (e) The heat generated at the heat generating point is converted into hydrogen gas, which is chemical energy, using a metal hydride, and the heat is sent to the heat utilization point and used to regenerate the heat. It becomes possible to make the heat temperature level exactly the same as the generated heat temperature level.
また、熱輸送は水素ガスにより行なわれるため、輸送中
の熱損失は水素ガスの顕熱損失に限られる。Furthermore, since heat transport is performed by hydrogen gas, heat loss during transport is limited to sensible heat loss of hydrogen gas.
そのため、輸送配管の距離は、はとんど問題とならない

高い断熱処理は必要とされず、安全面からの断熱処理（

The hydrogen gas only needs to be exposed (the pipes near the heat generation point will become hotter).

At the same time, the metal hydride containers 9B and 7B, which were in the regeneration process, are switched to the heat transport process, and heat at the heat collection temperature level is recovered from the container 9B in the heat regeneration unit 9.

体効率も約０．５となる。On the other hand, in the heat transport of this example using metal hydride, the heat loss in the hydrogen piping is small (heat loss: 2,000 kca Q /hr or less), so heat transport is possible with high efficiency. . However, due to the switching of the two metal hydride vessels of the heat transport unit and the collection and regeneration unit, which are required for continuous operation, the thermal efficiency is reduced, so that the overall efficiency is also about 0.5.
